188 J. H. Emerton — ISTew England Drassidm, 



short slender tube resting against the tip of the tarsus. Behind the 

 tube is a thin hooked process, and on the inner side a long process 

 with small black teeth at the end, fig. 4, 4a, \h, 4c. 



The epigynum has a long transverse opening a little in front of 

 the fold, fig. 4f?. 



Massachusetts, and Meriden, Conn. 



Phrurolithus Koch and Westring. 



Micariosoma Simon. 



Small spiders sometimes with bright markings and iridescent 

 scales. The legs of the first and second pairs have a double row of 

 strong spines under the tibia and metatarsus. PI. vi, fig. bh. The 

 maxillae are short and wide. The palpi of the males are very large 

 compared with the size of the spider, and have a long stout process 

 on the outer side of the tibia. The arrangement of the eyes and the 

 pattern of the dorsal markings resemble those of jLgroeca. 



Phrurolithus pugnatus, new sp. 



Plate VI, figfres 6, &a, 6&, 6c. 



2™"^ to 3'"™ long. Cephalothorax round, narrowed at the head as 

 in alarius. Abdomen usually shorter and rounder than in alarms. 

 PI. VI, fig. 6. Cephalothorax and legs bright yellowish brown. 

 Abdomen dark brown with transverse light markings which vaiy in 

 different individuals. Light yellowish beneath, except around the 

 spinnerets and epigynum. 



Epigynum with two oblique openings at the front end fai-thest 

 from the transverse fold. Parts of the })alpal organ are sometimes 

 found in the openings of the epigynum, fig. 6e. 



The male palpi are large in proportion to the size of the spider. 

 The femur has a short process near the base on the inner side. The 

 patella is as short as wide, but the tibia is nearly as large as the 

 tarsus and wider at the distal end. On its inner side is a long stout 

 tooth projecting forward, and on the outer side a longer curved one 

 as in P. alarius. The tibia is oval and the palpal organ short and 

 round, not extending backward at the base as in alarms, figs. 6a, 6b. 



Herpylliis parens Hentz resembles this species. 



Massachusetts and Connecticut.
